Based on the summary of the development situation of DIH dril ing rigs at home and abroad, this paper analyzes the luff-ing mechanism, one important part of DTH dril ing rigs,and the hydraulic system of its power and discusses its the basic structure. It also analyzes and simulates the pressure impact of its drive system exlsting in its operating process and uses the on simulation soft-ware AMESim to esfablish its model. The reason of the pressure impact is found through analysis. And according to the result of the simulation research, it proposes that the main valve is changed to increase its filter area. This scheme gives a reference to its im-provement and is of certain practical guiding significance.
